Motor Type and Rating

The Dayton 6K366 is a single-phase capacitor-start belt drive motor rated at 1/3 HP for 115/230V AC operation. It fits a standard 56 frame and runs at 1,725 RPM on 60/50 Hz supply. The rolled-steel frame and open dripproof enclosure suit industrial ventilation or fan accessories that need continuous duty.

Thermals, Noise and Power Draw

Class B insulation and a 1.35 service factor let the motor handle a maximum ambient temperature of 104 °F under continuous operation. Auto thermal protection cuts power if windings overheat. Full-load current is 5.7 A at 115 V or 2.8 A at 230 V, so circuit sizing follows the chosen voltage.

Mounting and Wiring Flexibility

A cradle base allows all-angle mounting and the shaft rotates both clockwise and counter-clockwise. The 5/8 in. shaft diameter matches common pulleys for belt-driven fan assemblies. Dual-voltage leads let the installer select 115 V or 230 V without extra components.

Questions about this item

How do I wire the 115/230V dual-voltage motor for 230V operation?

Reconfigure the internal terminal connections per the wiring diagram on the nameplate to match the 230V setting; the motor will then draw 2.8 A full-load current.

What routine maintenance does the open driproof enclosure need?

Periodically clean dust from the ventilation openings and verify the automatic thermal protection resets correctly after any overload event.

At what ambient temperature does the Class B insulation reach its limit during continuous duty?

The maximum rated ambient temperature is 104 Degrees F; sustained operation above this value will exceed the insulation class rating.
